Abstract In 2018, 100 years had passed since the Central Statistical Office of Poland (since 2017: Statistics Poland – GUS) was established. This anniversary was considered an opportunity for preparation of a series of cartographic publications, i.e. 16 statistical atlases of Polish voivodships (first order administrative units) and the Statistical atlas of Poland. Publication of such a series of atlases is a new undertaking in the history of Polish statistics – it involved both the employees of the head office of Statistics Poland in Warsaw and the staff of statistical offices in 16 voivodships. Until 2018 Polish public statistics did not have many such publications. The first atlas publication of Central Statistical Office was Republic of Poland – statistical atlas released in 1930. The next Statistical atlas, covering all of Poland, was published only in 1970. Subsequent statistical atlases were published over 30 years later – the atlases of five voivodships, published in 2006−2016, and the Demographic atlas of Poland published in 2017. Atlases for individual voivodships were prepared by the relevant regional statistical offices. The project was managed by the head office of Statistics Poland which prepared the guidelines and provided technical and substantive supervision. Due to different sizes of voivodships, the atlases were prepared in scales from 1:900,000 (Opolskie and Świętokrzyskie Voivodships) to 1:1,500,000 (Mazowieckie and Wielkopolskie Voivodships). A standard page contains a map of a voivodship divided into communes (gminas) or counties (powiats) and a map of Poland at the scale of 1:9,500,000 divided into voivodships. The number of pages of the voivodship atlas is 104 with 165 maps: 76 maps of voivodships, 76 maps of Poland, one administrative map of Poland at the scale of 1:3,800,000 and 12 maps of the European Union or Europe at the scale of 1:21,500,000. The Statistical atlas of Poland was published in early July 2018. It consists of 216 pages, with 281 maps (full-page maps of Poland at the scale of 1:3,800,000, quarter-page maps of Poland at the scale of 1:9,000,000, full-page maps of Europe or the European Union at the scale of 1:21,500,000, and half-page world maps at the scale of 1:200,000,000) and 175 charts/graphs. Maps made by using quantitative cartographic presentation methods predominate in the atlas – choropleth and diagram methods are used most frequently (they are observed on 263 maps). Statistical atlases of voivodships and the Statistical atlas of Poland count 1888 pages in total with 2934 maps, on which the development of the country is presented in relation to regional and local conditions. All atlases are bilingual, Polish-English. Publications printing was co-financed from EU funds within the Operational Programme Technical Assistance 2014–2020. Atlases are also available free of charge in the PDF format on the website of Statistics Poland: https://stat.gov.pl/statystyka-regionalna/publikacje-regionalne/podr
2018年,波兰中央统计局(自2017年起:Statistics Poland - GUS)成立100周年。这个周年纪念被认为是编写一系列地图出版物的机会,即16个波兰省(一级行政单位)统计地图集和波兰统计地图集。出版这一系列地图集是波兰统计史上的一项新工作- -它涉及华沙波兰统计局总部的雇员和16个省的统计办公室的工作人员。直到2018年,波兰的公共统计数据还没有很多这样的出版物。中央统计局出版的第一本地图集是1930年出版的《波兰共和国统计地图集》。下一个涵盖整个波兰的统计地图集直到1970年才出版。随后的统计地图集在30多年后出版,其中五个省的地图集于2006 - 2016年出版,波兰的人口地图集于2017年出版。个别省份的地图集由有关的区域统计处编制。该项目由波兰统计局总部管理,该总部负责编写准则并提供技术和实质性监督。由于省的大小不同,地图集的比例尺从1:90万(Opolskie省和Świętokrzyskie省)到1:15万(Mazowieckie省和Wielkopolskie省)不等。标准的一页包含一个省划分为公社(gminas)或县(powiats)的地图,以及一幅按1:9,50万比例尺划分为省的波兰地图。省地图集共104页,共165幅地图,其中76幅是省地图集,76幅是波兰地图集,1幅是波兰行政地图集,比例尺为1:38万,12幅是欧盟或欧洲地图集,比例尺为1:21万。《波兰统计地图集》于2018年7月初出版。全书共216页,地图281张(全页波兰地图,比例尺为1:38万;四分之一页波兰地图,比例尺为1:90万;全页欧洲或欧盟地图,比例尺为1:21万;半页世界地图,比例尺为1:20亿),图表175张。使用定量制图方法绘制的地图在地图集中占主导地位-最常用的是地图面和图解方法(在263幅地图上观察到它们)。各省统计地图集和波兰统计地图集共有1888页,其中有2934幅地图,根据区域和地方情况介绍了国家的发展情况。所有的地图集都是双语的,波兰语-英语。出版物印刷由2014-2020年业务方案技术援助内的欧盟资金共同资助。在波兰统计局的网站上也可以免费获得PDF格式的地图集:https://stat.gov.pl/statystyka-regionalna/publikacje-regionalne/podreczniki-atlasy/atlasy/。

Abstract The article presents the person and works of Georgy Voronoi (1868-1908), the inventor of an original method of diagrams, a student of the famous mathematician Andrey Markov. Georgy Voronoi graduated from the Department of Physics and Mathematics at the University of St. Petersburg, and subsequently worked as a professor of mathematics at the Imperial University of Warsaw. One of his students was the future outstanding Polish mathematician Wacław Sierpiński. In his brief lifetime G. Voronoi published several important scientific articles on number theory. In an almost 100 page paper in French published in 1908 he described a method of diagrams, or polygons, which became known as the method of Voronoi diagrams. In the digital age this method and its modifications found new applications. The entry “Voronoi” is getting more popular on the Internet, and the method of Voronoi diagrams and its modifications are widely described in handbooks and scientific articles. The article presents application of the method in the most popular computer programs from the Geographic Information System (GIS) group and presents examples of its usage in research on geographic space in various scientific disciplines.
摘要本文介绍了著名数学家安德烈·马尔科夫的学生、独创图解法的发明者乔治·沃罗诺伊(1868-1908)的生平和作品。乔治·沃罗诺伊毕业于圣彼得堡大学物理与数学系,随后在华沙帝国大学担任数学教授。他的一个学生就是后来杰出的波兰数学家Wacław Sierpiński。沃罗诺伊在他短暂的一生中发表了几篇关于数论的重要科学文章。在1908年用法语发表的一篇近100页的论文中,他描述了一种图表或多边形的方法,这种方法后来被称为沃罗诺伊图表方法。在数字时代,这种方法及其修改找到了新的应用。“Voronoi”这个词条在互联网上越来越流行,各种手册和科学文章中都广泛描述了Voronoi图的方法及其修改。本文介绍了该方法在地理信息系统(GIS)组中最流行的计算机程序中的应用,并举例说明了该方法在不同科学学科的地理空间研究中的应用。

Abstract Nigeria has a vast array of both natural and cultural tourist attractions. The country’s tourism industry, however, remains grossly underdeveloped, and the tourism resources are largely untapped. Hence, the tourism sector of the economy is yet to contribute significantly to the national Gross Domestic Product (GDP). One major factor that is responsible for the nation’s current lacklustre performance of the tourism sector is the poor state of tourism packaging and promotion, which, amongst other things is caused by the lack of appropriate tourist maps. Tourism mapping is a key component of tourism planning, development, promotion and management. For Nigeria to drastically and significantly improve the fortunes of her tourism sector, the production, circulation and use of accurate, current and comprehensive tourist maps and atlases must be vigorously pursued. To ensure sustainable tourism mapping and in line with global best practices, the country needs to adopt a Geoinformation technology-based, Internet-compatible multimedia cartographic approach. The author of this paper, therefore, examines the current state of tourism industry and tourism mapping in Nigeria. Some of the hiccups to tourism mapping in the country are identified. The implications of the present poor state of tourism mapping on tourism planning, development, promotion and management in the country are briefly considered. The author makes a strong case for the adoption of a multimedia cartographic approach to tourism mapping in Nigeria. A case of mapping wildlife parks in Nigeria is presented to demonstrate the prospects of effective multimedia tourism mapping of the country. Furthermore, the author identifies and discusses various existing resources in the country that could be harnessed for efficient and sustainable production, distribution and use of multimedia tourist maps/atlases, using Geographical Information Technologies (GIT). Some potential challenges to effective GIT-based tourism mapping in the country as well as how such challenges could be overcome, are equally discussed. Similarly, a model for Web-based, multimedia tourism mapping using GIT is presented. With clear vision, the right policy instrument, mandate, legislation, funding and coordination in place, the current challenges to effective and sustainable tourism mapping in Nigeria can easily be surmounted.
尼日利亚拥有大量的自然和文化旅游景点。然而,该国的旅游业仍然严重欠发达,旅游资源在很大程度上尚未开发。因此,经济的旅游部门尚未对国家国内生产总值(GDP)作出重大贡献。一个主要的因素,是负责国家目前的旅游业表现平平的旅游包装和推广,其中,除其他外,是由于缺乏适当的旅游地图造成的。旅游测绘是旅游规划、开发、推广和管理的重要组成部分。尼日利亚要大幅度和显著地改善其旅游业的命运,就必须大力制作、流通和使用准确、最新和全面的旅游地图和地图册。为了确保旅游制图的可持续性,并与全球最佳做法保持一致,该国需要采用基于地理信息技术、与互联网兼容的多媒体制图方法。因此,本文的作者考察了尼日利亚旅游业和旅游测绘的现状。确定了该国旅游地图绘制的一些问题。简要地审议了目前旅游制图状况不佳对该国旅游规划、发展、促进和管理的影响。作者提出了一个强有力的案例,采用多媒体制图方法在尼日利亚旅游制图。以尼日利亚野生动物公园为例,展示了该国有效的多媒体旅游测绘的前景。此外,作者确定并讨论了利用地理信息技术(GIT)可以有效和可持续地制作、分发和使用多媒体旅游地图/地图集的各种现有资源。同样讨论了在该国有效地进行基于信息技术的旅游测绘的一些潜在挑战以及如何克服这些挑战。同样,本文还提出了一个基于web的多媒体旅游地图模型。有了清晰的愿景、正确的政策工具、授权、立法、资金和协调,尼日利亚目前在有效和可持续的旅游测绘方面面临的挑战可以很容易地克服。

Abstract The author discusses a phenomenon of putting the works of military cartography on medals cast in the 17th century. The analysis focused on a medal presented to Krzysztof Arciszewski (1592-1656) by the Dutch West India Company in 1637. The obverse of this medal features two cartographic images depicting the siege of the Arraial Velho do Bom Jesus fortress (1635) and the battle between Camarigibi and Porto Calvo (1636). They were patterned after two manuscript maps. The maps were made by Arciszewski and attached to a memorandum written and sent to the management of the West India Company on 13 June 1633. They were engraved and published in print only around 1644. The plan of the battle that took place on 18 January 1636 indicates that the engraver (author unknown) used not only the manuscript version but also the medal. The example of the medal minted in 1637 confirms the credibility of cartographic representations featured on numismatic items. It should, naturally, be borne in mind that such representations must have been simplified due to the very nature of the means. Nevertheless, should there be no proper manuscript pattern, such objects may be used successfully as valuable cartographic sources.
摘要:本文讨论了17世纪铸造的勋章上印有军事地图学作品的现象。分析的重点是1637年荷兰西印度公司赠送给krzysztofarciszewski(1592-1656)的一枚奖章。这枚奖章的正面有两幅地图图像,描绘了对Arraial Velho do Bom Jesus要塞的围攻(1635年)和卡马里吉比与卡尔沃港(1636年)之间的战斗。它们是根据两份地图手稿绘制的。这些地图由阿奇舍夫斯基绘制,并附在一份备忘录上,于1633年6月13日送交西印度公司管理层。它们是在1644年左右雕刻和印刷的。1636年1月18日的战斗计划表明,雕刻家(作者不详)不仅使用了手稿版本,还使用了勋章。1637年铸造的这枚纪念章证实了钱币上的地图图案的可信性。当然,应当记住,由于手段本身的性质,这种表述必须加以简化。然而,如果没有适当的手稿模式,这些物体可能被成功地用作有价值的地图资源。

Continuous or discontinuous? Empirical study on animated maps 连续的还是不连续的?动画地图的实证研究
Pub Date : 2018-09-01 DOI: 10.2478/pcr-2018-0008

Abstract Advancements in computer technology that have occurred in recent decades have enabled an intensive development in cartographic methods for direct representation of phenomena dynamics. Even with the appearance of ever more advanced technical solutions, the theoretical basis still needs supplementing. The previous cartographic literature emphasises the importance of congruence and isomorphism principles preservation that aims at increasing the effectiveness of dynamic displays. Nevertheless, it is frequently the case that discontinuous phenomena are depicted with the use of smooth transitions. For this reason, it is vital that experimental research should lead to defining which representation methods are appropriate for a given type of content. Our study was focused on the cartographic design of scene transitions in animated maps. Two main conclusions of the research indicate that 1) mode of transition influences the interpretation of the content of cartographic animation depicting discrete changes, 2) maps executed in a smooth mode demonstrate lower effectiveness when compared with animations using an abrupt and abrupt with decay effect transitions.
近几十年来,计算机技术的进步使直接表示现象动力学的制图方法得到了广泛的发展。即使出现了越来越先进的技术解决方案,理论基础仍然需要补充。以前的制图文献强调了一致性和同构原则保存的重要性,旨在提高动态显示的有效性。然而,通常情况下,不连续现象是用平滑过渡来描述的。因此,至关重要的是,实验研究应该导致定义哪种表示方法适合给定类型的内容。我们的研究重点是动画地图中场景转换的制图设计。研究的两个主要结论表明:1)过渡模式影响对描绘离散变化的地图动画内容的解释;2)与使用带有衰减效应的突然和突然过渡的动画相比,以平滑模式执行的地图显示出较低的有效性。

Abstract Built-up area is a particularly important element of the content of topographic maps. Its presentation changes significantly when map scales are reduced, due to both conceptual and graphic generalization. What is more, historically, changes in the depiction of built-up area were consequences of changes in the intended use of topographic maps, development of technology and changes in the cultural landscape, of which the built-up area is an important component.1 The authors describe the method of presentation of built-up areas on six Polish topographic maps or series of maps. The above-mentioned maps include the following: – Topograficzna Karta Królestwa Polskiego (Topographic Map of the Polish Kingdom) at the scale of 1:126,000 developed in 1822–1843; – topographic maps of the Polish Military Geographical Institute (MGI) at the scales of 1:25,000 and 1:100,000, published in 1930s; – a series of military maps (or military-civilian maps) at the scales of 1:10,000, 1:25,000, 1:50,000 and 1:100,000, developed in 1956–1989, in accordance with the instruction for developing Soviet maps; – a series of civilian maps at the scales of 1:10,000, 1:25,000, 1:50,000 and 1:100,000 developed after 1995. The basis for a quantitative comparison of the content of the maps was the number of categories of objects (identifications) which constitute part of built-up area and are presented on individual maps as symbols, as well as the number of characteristics represented by these symbols. These characteristics are divided into two basic types: functional characteristics and physiognomic characteristics. The analysis shows that military maps issued after the Second World War differ from the civilian maps, as they contain a much larger share of physiognomic characteristics, which is caused mainly from the fact that the vast majority of military maps distinguish between wooden and brick buildings. This difference was to large extent already noticeable among the oldest of the analysed maps – the Quartermaster’s Map and nineteenth-century Russian maps, which were partly modelled on the Quartermaster’s Map, and later also Soviet maps. Due to political reasons, the model of these Soviet maps was later adopted for the development of post-war Polish military maps. Out of all maps drawn up by military services, the inter-war MGI map serves special attention, as it was modelled on German maps. The main difference between military and civilian maps is foremost the fact that civilian maps include more functional characteristics of buildings and take into consideration new physiognomic characteristics related to residential development (compact, dense, multifamily dwellings, single family dwellings). The analysed maps include not only the characteristics of buildings and built-up area, but also information on the features of the town – population size, number of village houses and the administrative function.
建成区是地形图内容中一个特别重要的组成部分。由于概念和图形的一般化,当地图比例尺缩小时,它的呈现方式会发生显著变化。更重要的是,从历史上看,建成区描述的变化是地形图预期用途的变化、技术的发展和文化景观变化的结果,而建成区是其中的一个重要组成部分作者描述了在六幅波兰地形图或系列地图上展示建成区的方法。上述地图包括以下内容:-《波兰王国地形图》(Topograficzna Karta Królestwa Polskiego),比例尺为1:12 . 6 000,绘制于1822年至1843年;- 1930年代出版的波兰军事地理研究所1:25 000和1:10万比例尺的地形图;-一系列军用地图(或军民地图),比例尺为1:10万、1:25万、1:5万和1:10万,1956-1989年根据苏联地图制作指示制作;-在一九九五年以后,以1:10万、1:25万、1:5万及1:10万的比例尺制作一系列民用地图。对地图内容进行数量比较的基础是构成建成区一部分并在个别地图上作为符号表示的物体类别(标识)的数量,以及这些符号所代表的特征的数量。这些特征分为两种基本类型:功能特征和面相特征。分析表明,第二次世界大战后发行的军用地图与民用地图不同,因为军用地图包含更多的地貌特征,这主要是由于绝大多数军用地图区分了木制和砖砌建筑。这种差异在被分析的最古老的地图——《军需官地图》和19世纪的俄罗斯地图,以及后来的苏联地图——中已经在很大程度上显而易见。由于政治原因,这些苏联地图的模型后来被用于战后波兰军事地图的开发。在所有由军事部门绘制的地图中,战争期间的MGI地图特别引人注目,因为它是以德国地图为模型绘制的。军用地图和民用地图的主要区别在于,民用地图包含了更多建筑物的功能特征,并考虑了与住宅开发相关的新地貌特征(紧凑、密集、多户住宅、单户住宅)。所分析的地图不仅包括建筑物和建成区的特征,还包括城镇的特征信息——人口规模、村屋数量和行政职能。

Abstract Peruvian cartography in the nineteenth century was very rich and fulfilled the geographic knowledge demanded by the new Republic of Peru. In effect, the country of more than 1,000,000 km2 needed to show the physical environment and to locate the distribution of its natural resources. It was the time when cartography was valued as an element of empowerment and land control, especially when the political borders were rather unstable (G. Prieto 2018). Then, it was timely the publication of Atlas Geográfico del Perú (Geographic Atlas of Peru) by Mariano Felipe Paz Soldán, a prominent Peruvian lawyer and geographer. Author’s purpose is to comment on the new edition of the Mariano Felipe Paz Soldán Atlas Geográfico del Perú, published in Lima in 2012.
19世纪秘鲁的地图学非常丰富,满足了新秘鲁共和国对地理知识的需求。实际上,这个面积超过100万平方公里的国家需要显示其自然环境并确定其自然资源的分布。在那个时代,制图被视为赋权和土地控制的一个要素,尤其是在政治边界相当不稳定的情况下(G. Prieto 2018)。当时,秘鲁著名律师和地理学家马里亚诺·费利佩·帕斯Soldán出版了《秘鲁地理地图集Geográfico del Perú》。作者的目的是对2012年在利马出版的新版Mariano Felipe Paz Soldán Atlas Geográfico del Perú发表评论。

Abstract The paper discusses selected maps of rock strata which exemplify the evolution stages of presentation methods of cartographic data concerning the geological structure of selected countries (France, Great Britain and Germany) which in the first half of the nineteenth century constituted the leaders of the field. The results of geologists’ work are used to present the content of maps, provide explanations and showcase the methods and techniques chosen by the maps’ creators. The analysed maps are accompanied by geological writings which contain descriptions of the chronological order within rock formations and strata defined on the basis of fossils, methods of recreating the geological history of individual regions, and attempts of compiling the acquired knowledge and using it to describe larger areas. The author discusses also two maps of Europe published in the mid-nineteenth century, which are the result of cooperation and research achievements of geologists from different countries.

Pub Date : 2018-07-01 DOI: 10.2478/pcr-2018-0004
Jordan Tzvetkov
Abstract The aim of the article is to present different relief visualization techniques created using only free and open source GIS tools, such as QGIS and RVT. The criteria for selection of these techniques are that they should be, on the one hand, simple and fast for implementation and on the other suitable for multiple visualization purposes. Here we present several techniques which combine hillshade with other relief data layers derived from DEM and an assessment of advantages and disadvantages of their visualization.

‘Partially compiled’ maps 1:25,000 by Polish Military Geographical Institute (1919–1939) 波兰军事地理研究所(1919-1939)“部分编辑”1:25 000地图

Abstract During the interwar period, an estimated 32–36% of Polish territory was covered by the Polish Military Geographical Institute’s (Pol. Wojskowy Instytut Geograficzny) 1:25,000 detailed map. At the same time, the MGI achieved a full coverage of the country by 1:100,000 tactical map. 50% of tactical map sheets were revised for the 1930s – many covered areas for which no detailed maps had been printed. Considering the fact that 1:100,000 tactical map was updated on the basis of revised 1:25,000 maps, another 17–21% of 1:25,000 detailed map sheets were finished or in progress by the German and Soviet invasion in 1939. The study confirmed additional 4% of 1:25,000 detailed map sheets as ‘partially compiled’ by the MGI and finished by the Germans. Another 17% of detailed map sheets are potentially to be found. Hypotheses, clues and evidence are presented in the paper.
